Story Shear (Response Spectrum Analysis) Table

Check the story inertia forces and story shear forces from the response spectrum analysis results in a spreadsheet format table.

When "Story Shear Force Ratio>Consider Story Module"is checked in the "Model/Building/Control Data", accurate shear forces can be obtained for the story having the overlapping Module.

When Modules are defined in Results > Result Tables > Story > Define Module, the Module data is displayed in the first column of the table.

Results Table

From the Main Menu select Results > Result Tables > Story > Story Shear(Response Spectrum Analysis).

Select Result Tables > Story > Story Shear(Response Spectrum Analysis) in the Tables tab of the Tree Menu.

From the Records Activation Dialog, select the Spectrum Load Cases for which story shear forces will be checked.

Refer to Usage of Table Tool and check the following data:
 

    When Modules are not defined

Story Shear (for R.S)

Story Shear (for R.S) tab

Story: Story ID

Level: Story Elevation

Spectrum: Response spectrum load case

Inertia Force: Story inertia force

Shear Force: Story shear force

Spring Reaction: Reaction of a spring entered as a boundary condition (linear spring support)

Without Spring: Story shear force less the spring reaction

With Spring: Story shear force including the spring reaction

Note
The story inertia force is calculated from the member forces of the relevant story.

Eccentricity: Eccentricity from the mass center

Story Force: Shear force at each story level

Note

Shear Force represents the sum of shear forces of all the upper stories as well as the corresponding story, and Story Force represents the shear force acting on the corresponding story.

Eccentric Moment: Story Shear * Eccentricity

Note
These items are produced only when we apply 'Consider Accidental Eccentricity' in Load > Response Spectrum Analysis Data > Response Spectrum Load Cases.

Story Shear Force Coefficient

Story Shear Force Coefficient tab

Story: Story ID

Spectrum: Response spectrum load case

Shear Force: Story shear force

Weight Sum: Total weight

Story Shear Force Co: Story shear force coefficient

Note
Produce the Story Shear Force Coefficient of (Roof level - 1) by dividing the story shear force of (Roof level-1) by the total weight of Roof level. The Story Shear Force Coefficient for roof level is ruled out. Base shear of a building structure divided by total weight will be the Story Shear Force Coefficient of bottom floor (1F).

Shear Force: Story shear force

Weight Sum: Total weight

Story Shear Force Co: Story shear force coefficient

Note
Produce the Story Shear Force Coefficient of (Roof level - 1) by dividing the story shear force of (Roof level-1) by the total weight of Roof level. The Story Shear Force Coefficient for roof level is ruled out. Base shear of a building structure divided by total weight will be the Story Shear Force Coefficient of bottom floor (1F).
